11:01 Calibration Curve for AAS
Syllabus
conduct investigations and/or process data to determine the concentration of coloured species and/or metal ions in aqueous solution, including but not limited to, the use of:
– colourimetry
– ultraviolet-visible spectrophotometry
– atomic absorption spectroscopy
What is AAS? How does AAS work? What is a calibration curve? AAS example. How to measure concentration of metal ions using AAS. What are the components of AAS: monochromator, hollow cathode lamp and flame atomiser.
